Title: Method and apparatus for moving a shaft into a predetermined angular position
IPC: B23Q15/26
Filed: 1971-10-05
Abstract: A method and apparatus through which a moving shaft is stopped in a predetermined angular position. The shaft is driven at a maximum speed through an electrically driven motor. When the shaft is to be stopped at the predetermined angular position, the shaft is decoupled from the motor and an electromagnetic brake is applied. A regulating circuit controls the braking action so that it is dependent on a comparison of the actual output speed of the shaft and a desired input speed, as well as the comparison of a computed braking angle and the predetermined angular position to which the shaft is to be rotated. Position and speed sensors connected to the shaft provide signals representing the instantaneous output position and speed of the shaft.

Patent ES-412476-A1 (ES)
Title: Semiconductor controlled magneto ignition system for internal combustion engines
IPC: H02K21/12
Filed: 1973-03-09
Abstract: A magneto generator is driven by the engine and provides output energy which varies with change in engine speed. The output energy is applied to an energy storage device, typically a capacitor, which is charged and, when a semiconductor switching element is rendered conductive, the stored energy is used to generate the spark of the spark plug. In order to provide for spark-advance as the speed of the engine increases, the magneto generator is wound to provide two half waves of output which are sequential, in time, for example by having two oppositely phased windings, or a center tapped winding, from which half waves are obtained, the first being of lesser amplitude than the second. During slow speed operation, only the second half wave will trigger the semiconductor to provide a spark discharge upon high-speed operation, sufficient amplitude is derived from the first winding so that the spark will be triggered earlier, thus providing for spark-advance upon high-speed engine operation.

Title: Temperature compensating bias circuit
IPC: D01D5/30
Filed: 1980-03-14
Abstract: A biasing circuit is provided for stabilizing the gain of a transistor amplifier against variations in temperature. The amplifier includes an input terminal and a transistor having a base-to-emitter junction coupled between the input terminal and the second terminal of a two-terminal source of supply potential. The biasing circuit is coupled between the two supply terminals and includes a resistor coupled to the first terminal, a semiconductor rectifying junction coupled between the input terminal of the amplifier and the second supply terminal, and the parallel combination of the collector-to-emitter path of a second transistor and a voltage divider coupled between the resistor and the rectifying junction. The base of the second transistor is coupled to an intermediate tap of the voltage divider. As the temperature of the circuit increases, the gm of the amplifying transistor decreases. The biasing circuit conducts an increasing amount of current to the amplifier as the operating temperature of the circuit increases. This increase in biasing current causes an increase in the collector current of the amplifying transistor, which stabilizes the gm and hence the gain of the amplifier.
